Description

Technical Field

[0001] The utility model relates to the field of molds, and in particular to a structure of a combined mold hanging column. Background Art

[0002] At present, a Chinese patent with the authorization announcement number CN203212211U discloses a hoisting device, which includes a lifting ring, a lifting shaft, a sling, and a mold reinforcing rib. The lifting ring is placed in the middle of the mold reinforcing rib. The lifting shaft passes through the holes of the mold reinforcing rib and the lifting ring and is directly hoisted. The sling is fixedly connected to the lifting ring. In addition, it also includes a groove provided on the upper surface of one end of the lifting shaft, and a buckle fixed in the groove. The buckle is a frustum with an opening inside.

[0003] Among them, the lifting ring is usually fixed to the mold in a threaded connection manner. And since the lifting ring is placed on the upper surface of the mold, when the lifting ring is hoisted, only the tensile force is applied to the mold by the thread, and it is extremely easy to cause wear and damage to the thread. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a structure of a combined mold hanging column to achieve the purpose of greatly extending the service life.

[0005] To solve the above technical problems, the technical solution of the utility model is: a structure of a combined mold hanging column, which includes a mounting column, a fixing column, a connecting column, a guard plate, and a mounting hole opened on the side wall of the mold. The mounting column, the fixing column, the connecting column, and the guard plate are fixedly connected in sequence. The mounting column penetrates into the mounting hole, and an interference fit is provided between the mounting column and the mounting hole. The outer diameter of the fixing column is larger than that of the mounting column, the outer diameter of the connecting column is smaller than that of the mounting column, the outer diameter of the guard plate is larger than that of the connecting column, and the mounting column, the fixing column, the connecting column, and the guard plate are coaxially arranged.

[0006] To implement the above technical solution, the mounting hole is opened on the side wall of the mold, the mounting column is embedded into the mounting hole, a chain is passed around the connecting column so that the chain is located between the fixing column and the guard plate, and a tensile force is applied to the chain, then the mold can be hoisted. And because the mounting column abuts against the inner wall of the mounting hole to apply a force to the mold, the wear between the mounting column and the mounting hole is relatively small, greatly extending the service life; even if the mounting column is worn due to long-term use and the interference fit between the mounting column and the mounting hole develops into a transition fit, it still has a good supporting effect.

[0007] As a preferred scheme of the utility model, a first arc surface is provided between the connecting column and the fixing column, and a second arc surface is provided between the connecting column and the guard plate.

[0008] To implement the above technical solution, through the guiding action of the first arc surface and the second arc surface, the chain can move towards the middle of the connecting column, so that the chain is not likely to move on the connecting column, improving the stability of the chain during the lifting process.

[0009] As a preferred embodiment of the present utility model, a placement plane is provided on the side wall of the fixed column, a pulling hole is provided on the placement plane, the extension line where the axis of the pulling hole is located is perpendicular to the axis of the fixed column, a connecting rod is threadedly connected to the pulling hole, a pulling rod is fixedly connected to the connecting rod, and the end of the pulling rod abuts against the placement plane.

[0010] To implement the above technical solution, the pulling rod is threadedly connected to the pulling hole through the connecting rod, and a force along the axial direction of the mounting column is applied to the pulling rod to facilitate the extraction of the mounting column from the mounting hole.

[0011] As a preferred embodiment of the present utility model, a sliding hole is provided on the pulling rod along its own axis, a boosting rod is slidably connected to the sliding hole, and the sliding hole is connected to the boosting rod through a limiting structure.

[0012] To implement the above technical solution, the boosting rod is slidably connected to the sliding hole, and the boosting rod is positioned through the limiting structure to reduce the occupied space volume and facilitate storage; the boosting rod is moved along the sliding hole away from the pulling rod and then positioned through the limiting structure, and the mounting column is extracted from the mounting hole through the boosting rod, which is more labor-saving.

[0013] As a preferred embodiment of the present utility model, the limiting structure includes a limiting hole, a positioning hole, and a positioning column. A plurality of the limiting holes are provided on the outer wall of the pulling rod and communicate with the sliding hole, the positioning hole is provided on the outer wall of the boosting rod and corresponds to the limiting hole, an elastic member is fixedly connected to the positioning hole, the positioning column is slidably connected to the positioning hole and one end is connected to the elastic member, and the other end penetrates into the limiting hole.

[0014] To implement the above technical solution, the boosting rod is inserted into the sliding hole. When the limiting hole corresponds to the positioning column, through the elastic force of the elastic member, the positioning column penetrates into the limiting hole. At this time, the inner wall of the limiting hole abuts against the positioning column to realize the limiting of the boosting rod; a pressure is applied to the positioning column to press the positioning column into the sliding hole, and the boosting rod can be moved along the length direction of the sliding hole to adjust the position of the boosting rod, and the operation is simple.

[0015] As a preferred embodiment of the present utility model, a first annular groove is provided on the side wall of the pulling rod, the first annular groove is coaxially arranged with the pulling rod, a second annular groove is provided on the outer wall of the boosting rod, and the second annular groove is coaxially arranged with the boosting rod.

[0016] To implement the above technical solution, the chain is hung on the first annular groove and / or the second annular groove, so as to apply pressure to the pull rod and / or the booster rod, so as to extract the mounting post from the mounting hole. During this process, the chain is not easily detached from the pull rod and / or the booster rod, improving stability.

[0017] As a preferred solution of the present utility model, an extension hole is provided on the guard plate, and the extension hole sequentially penetrates through the connecting post, the fixing post, and the mounting post. A top rod is threadedly connected in the extension hole, and the end of the top rod is used to abut against the bottom wall of the mounting hole.

[0018] To implement the above technical solution, the top rod is threadedly connected to the extension hole, and the end of the top rod abuts against the bottom wall of the mounting hole. Through the conduction of the thread, the mounting post is pushed out of the mounting hole, preventing the mounting post from being stuck in the mounting hole. BRIEF DESCRIPTION OF THE DRAWINGS
